Comparative Evaluation of Various Brands Ciprofloxacin HCI Tablets

Ciprofloxacin HCI, is a highly popular antibacterial agent in the third world countries including India. Many companies are engaged in manufacturing and marketing the brands, purchasing the basic drug from the core suppliers. Often these brands vary in cost and companies usually claim superiority of their product to justify the higher price. There is a possibility that products containing same amount of basic drug are therapeutically equivalent. So, if it can be proved that the different brands are therapeutically equivalent, they can be substituted for each in prescription and patient can be take advantage of an economic dosage regimen. This could be achieved by assessing physicochemical equivalence of different brands of the drug. Assessment may include the evaluation of uniformity of weight, friability, hardness, disintegration and dissolution tests as well as chemical assay of tablets.

Application of Mathematical Modeling in Population forecasting

In the present paper we have to study future population forecasting in India by the geometrical model used to census population data. Design is based on the projected population of India, estimated for the design period. Changes in population over the years occur, and the system should be designed into account of the population at the end of the design period. Factors affecting changes in population are increase due to births, decrease due to deaths, increase and decrease due to the migration and increase due to the annexation. The present and past population record in India can be obtained from the census population records. After collecting these population records, the population at the end of design period is predicted using various geometrical methods as suitable for the growth pattern.
